简介
Transformer winding DC resistance measurement is overhauled, followed by nonexcited switching converter tap, short circuit through the outlet 1 to 3 years will once again project. By direct resistance measurement, you can check out the quality of the welding wire or connection between the winding Haveturn short circuit or open circuit, and tap the contact is good and so on. Before direct resistance measurements are used to measure QJ44 double bridge, the bridge and the measurement of such currents is mA level measurement it takes a long time, but the accuracy is lower, for a limited Wuhan Guo Ding Technology the company developed a new type of direct resistance meter a transformer DC resistance tester ------ GDBY6803 DC resistance tester is suitable for measurement of transformer winding, transformers, motors and other inductive winding DC resistance of the sample, but also as a switch contact resistance, cable resistance and general resistance measurement tools, measurement of largecapacity threephase transformer winding DC resistance and optimize the design can be threephase transformer winding DC resistance test carried out at the same time, the DC resistance tester can be ACand DC dualuse. For the wild without AC power, is particularly applicabl
